The city of Zurich with its 403,000 inhabitants covers an area of 92 km² and is by far the lar- gest city in Switzerland. If you include the hea- vily populated immediate surrounding areas from which numerous commuters stream into the city each day, this conurbation is home to 1.3 million people. The city on the river Lim- mat and Lake Zurich is the country's most important economic and financial metropolis, its university and Institute of Technology have achieved international renown, and in terms of art and culture, the city is an important hub for Switzerland. Internationally, Zurich has been awarded city with the highest quality of life on several occasions, not least because of its well- preserved medieval district, its excellent geo- graphical position and incredible flair.
